I am using Emacs for Python developement. My team is using Tab indentation, so I must do the same. The problem is that I can't figure out how to make python-mode use tabs instead of spaces. I want Emacs to automatically indent my line to the correct level when I press Ctrl-j.

@user1129682, emacs is mostly written in LISP, and the above is a LISP statement adding a function to python-mode-hook, a list of functions to run when starting to edit Python code. What the apostrophe does is to tell LISP that python-mode-hook is the variable to modify, not its name.
